Set DynamoDBBillingMode and IOPS parameters per environment

**Is your feature request related to a problem? Please describe.**
I need to be able to set DynamoDBBillingMode and its related IOPS parameters on a per environment basis. Currently these are set in the parameters.json which sets them on the whole API for every environment.
For example our DEV environment only requires PROVISIONED and 1 Read/Write IOPS. Whereas in PRD we would prefer to set this to PAY_PER_REQUEST (or potentially PROVISIONED with higher IOPS).

**Describe the solution you'd like**
Set the parameters for DynamoDBBillingMode, DynamoDBModelTableReadIOPS, DynamoDBModelTableWriteIOPS in the team-provider-info.json so it can be done per environment instead of the parameters.json.
